Technical field
The present invention relates to tire production, relate more specifically to the assembling of rubber product on cylindrical.The tire that is used for motor vehicle is usually by placing the assembling drum to go up to make with the rubber molding element with by overlaying on rubber composition and strengthening cord with vertical weaving that forms specified angle or metal.
Background technology
Thereby assembling process is by the product in the continuous band cutting designated length zone that forms from forming element or reinforcement plies, should the zone on drum and should the butt joint of two ends, zone and form.
In this respect, the joint quality that is produced depends on the quality of being cut to a great extent when cutting this zone.
Though may expect to produce so-called end-to-end butt joint, wherein the end of the product that overlaps does not have overlapping.In this case, usually with small angle cutting forming element band with the contact area that increases two ends and the joint that obtains to have good tensile strength be wise.This band obtains reinforcement plies by strengthening between the line separately at two, should the zone reinforcement plies on the assembling drum after, by docking two ends end-to-end and connect along being positioned at cord on the otch both sides.These operate in needs very high accuracy when carrying out, make this regional length very accurately consistent with the laying circumference.
This is why preferably by making the overlapping a bit of distance in two ends connect the reason at forming element or reinforcement plies two ends.When the product that will dock has low thickness, this method advantageous particularly that carries out.
Usually, and in order to reduce assembly cost, formed product band and reinforcement plies are fitted together in advance or are assembled in advance on the reinforcement plies, the band that comprises different pre-completed knocked down products with formation is also very general.Thereby can simultaneously multiple product be laid on the assembling drum.
This practice causes selecting not having with the generation butt joint overlapping, makes the forming element of same nature or the end of reinforcement plies connect end-to-end, thereby prevent that product of different nature from overlapping each other on joint.
" different qualities " is interpreted as forming element or the reinforcement plies that expression has different physical-chemical and geometrical property.
In order to produce this montage piece, particularly, proposed a variety of shearings and apparatus for assembling or method, and the shearing of reinforcement plies has been had care very especially, thereby do not damaged the reinforcement cord in order to shear the pre-completed knocked down products that comprises reinforcement plies.
Communique US2004/0035271 has proposed a kind of device of distinctive appearance, and it is reinforcement plies fixedly, prevents that it is in the casing ply below, and can adopt the cutting of ultrasonic wave cutter, thereby make the cut surface of cutting products have different specified angles.In order to accomplish this point, cutting edge is introduced in the reinforcement plies, strengthens the interface between the cord and described cord is elevated to above cutting edge thereby cut two; By cutting along the horizontal mobile cutting edge of described cord.
Communique WO00/51810 discloses and has adopted two cutting edges, and one of them is positioned at the below on reinforcement plies plane, shear described reinforcement plies, and wherein another is positioned at the top on reinforcement plies plane, cuts the rubber molding element at a predetermined angle.
But these cutting methods can not produce cut-out, and making it possible in its front does not have the goods of different qualities to overlap each other on this joint by overlapping connection end.
Summary of the invention
Target of the present invention is to provide a solution for this problem.
The cutter sweep of target of the present invention comprises the cutting edge that forms three completely different zones, this makes it cut off reinforcement plies simultaneously, at reinforcement plies and interface between the rubber molding element and the rubber molding element itself assembled in advance on the described reinforcement plies.
